The original version should be Sons By Four's "Purest of Pain", which is pretty good. Though they seem like a one-hit wonder

Coco is pretty good, if she stops her screeching. Don't know is it because of her "Asian Mariah Carey" tag which makes her scream her lungs out in some songs, they certainly blast my eardrums sometimes.
I much prefer her old old songs like "Wang Ri Qing" and "Wo Yi Ran Shi Ni De Qing Ren". Very karaoke-ish, but at least they are sung with more technic and less screeching.
Think she should now be busy with continuing her invasion of the America market. Afterall, she did get quite alot of exposure from her stint on the "Crouching Tiger" soundtrack performed during the Oscars, so I guess people are lining up for her ?
